I obtained my PhD in Life Sciences from the University of Tübingen in Germany. My PhD research with Professor Stefan Gründer focussed on neurophysiology and ion channel receptors in particular neuronal Acid -Sensing Ion Channels (ASICs). Then I undertook postdoctoral studies on neuronal Voltage – Gated Calcium (Cav) Channels with Professor Annette Dolphin (FRS) at UCL. I also worked as a visiting researcher in UCLA in the laboratory of Professor Riccardo Olcese apply Voltage-Clamp Fluorometry (VCF), an optical technique to study functional domains of Calcium Channels in live cells. In February 2022 I took a lectureship position at the Queen Mary University of London to establish my research laboratory supported by the New Investigator Research Grant by the MRC (2022-2025). My research aims to understand the structure-function relationship, interactions, and cellular trafficking of neuronal and cerebrovascular voltage-gated calcium channels, and the mechanism of action of drugs that target these channels to maintain human health and prevent disease.
BIO333: Neuroscience: From Molecules to Behaviour
My group investigates the structure-function relationship, interactions, and cellular trafficking of neuronal and cerebrovascular Calcium Channel proteins by focussing on novel pathways for their biological regulation. Cav channels control vital physiological processes including neurotransmitter release, neuronal excitability, cardiac contraction, and vascular tone. Abnormal Cav channel regulation can lead to severe human diseases including neuropathic pain and cardiovascular dysfunctions and their studies can help to maintain human health and prevent disease.
